Mordenkainen's Tome of Foes

OB LEX

By experimenting on the slimes, jellies, and puddings

that infest the depths of the Underdark, mind flayers

created a special breed of ooze, the oblex- a slime capa-

ble of assaulting the minds of other creatures. Cunning

hunters, these pools of jelly stalk prey, searching for the

memories they so desperately crave. When oblexes feed

on those thoughts, sometimes killing their victims, they

can form weird copies of their prey, which help them to

harvest even more victims for their dark masters.

Memory Eaters. Oblexes feed on thoughts and mem-

ories. The sharper the mind, the better the meal, so

oblexes hunt obviously intelligent targets such as wiz-

ards and other spellcasters. When suitable fare comes

within reach, an oblex draws its body up to engulf its

victim. As it withdraws, it plunders the creature's mind,

leaving its prey befuddled and confused.

Ooze Nature. An oblex doesn't require sleep.

0BLEX SPAWN

An oblex devours memories not only to sustain its exis-

tence, but also to spawn new oblexes. Each time it fully

drains the memories of a victim, it gains the creature's

personality-now twisted by the oblex's foul nature. The

more memories an oblex steals, the larger it becomes,

until it must shed a personality it has absorbed or else

go insane. This act spawns a new oblex.

ADULT AND ELDER 0BLEXES

Newly formed oblexes lack the capabilities of their older

kin. They seek only to feed on memories and grow until

they can impersonate their victims.

Older oblexes, called adults and elders, have eaten

so many memories that they can form duplicates of

the creatures they have devoured from the substance

of their bodies, sending them off to lure prey into their

clutches, while remaining tethered to the slime by long

tendrils of goo. These duplicated creatures are indistin-

guishable from their victims except for a faint sulfurous

smell. Oblexes use these duplicates to lure prey into

danger or to infiltrate settlements so they can feed on

superior victims.
